Summary PV‐based and wired type of the electrical bicycles (e‐bike) battery charging stations widely is spreading because of the resonant network limitations and low efficiency of the wireless mode for these stations. The generated voltage of many of the PV panels such as JIYANGYIN HR‐200 W‐24 V at the maximum power point is around 36VDC. So, a step‐down converter with a PID controller for Maximum Power Point Tracking (MPPT) of the PV panels is considered between PV panels and boost converter in order to decrease this voltage and enhance the current values for the load side. A sliding mode controller (SMC) equipped with a non‐isolated DC‐DC boost converter with reduced voltage stresses on the power switch is presented. The step‐up converter increases the voltage to the utility level of the e‐bike with around 360 Wh amount of energy. The main concerns about the converters are the efficiency, voltage, and current stresses, number of active or passive components in the converter topology and simplicity. In comparison with a conventional step‐up converter, the selected converter has a lower dynamic loss in the input inductor that can give a proper efficiency by considering its higher voltage gain. The average state‐space model for the SMC is used and the main advantage of the controller is its independency to the inductor current or the amount of the load. The proposed SMC is compared with PID and Fuzzy Logic Controller (FLC) methods and based on the results, the robustness, overshoot, and damping factor of the controller are at an acceptable and better level. All mathematical, simulation and comparison results are presented. A 720 Wh circuit has been implemented for charging all types of the Li‐Ion or Li‐Polymer batteries with 36VDC and 10 Ah specifications.

“…No obstante, el control con banda de histéresis de ancho fijo causa que la frecuencia de conmutación sea variable de tal forma que se hace necesario aumentar el tamaño y el costo de los filtros, los inductores y los disipadores de calor del sistema (Huber et al, 2008). La frecuencia variable también puede producir ruido audible e incrementar las pérdidas de potencia cuando el voltaje de la fuente tiene amplitud baja y la frecuencia de conmutación es alta (Ye et al, 2014;Guzman et al, 2016;Chincholkar y Chan, 2017;Pichan y Rastegar, 2017;Repecho et al, 2017).…”

“…Varios autores reducen el rizado fijando la frecuencia de conmutación; sin embargo, las metodologías de control presentadas deterioran el desempeño dinámico y la robustez del sistema (Mohanty y Panda, 2017;Ye et al, 2014;Chincholkar y Chan, 2017;Guzman et al, 2016;Pichan y Rastegar, 2017;Ye et al, 2014;Ashita et al, 2014). Además, el sistema de control requiere alta capacidad de cómputo que usualmente incluye unidades de punto flotante y arquitecturas de memoria de acceso múltiple para realizar los cálculos necesarios para fijar la frecuencia, incrementando los costos de la implementación.…”

ResumenSe propone aplicar una banda de histéresis adaptativa que permite reducir la distorsión armónica total, el rizado y la deformación en el cruce por cero de la corriente de entrada de un convertidor AC-DC elevador sin puente con corrección del factor de potencia (PFC, Power Factor Correction). Se presenta un procedimiento para calcular la banda de histéresis con base en los estados dinámicos del convertidor electrónico de potencia, de tal forma que es posible fijar la frecuencia de conmutación. La banda es aplicable al control por modos deslizantes que permite mejorar el desempeño dinámico de los convertidores ante perturbaciones acotadas y cambios significativos de la región de operación. Se presentan los resultados de la simulación de un convertidor de 1 kW. Se muestra que es posible elevar el factor de potencia hasta 0.996, disminuir la deformación del cruce por cero, y reducir la distorsión armónica total en la corriente de entrada hasta 2.8 %, manteniéndola por debajo de los límites máximos permisibles del estándar EN/IEC 61000-3-2 (1000-3-2). AbstractIt is proposed to apply an adaptive hysteresis band that allows to reduce the total harmonic distortion, the ripple and the deformation in the zero crossing of the input current of a bridgeless boost AC-DC converter with power factor correction (PFC). A procedure for calculating the hysteresis band based on the dynamic states of the converter is presented, in such a way that it is possible to keep fixed the switching frequency. The band is applicable to the sliding mode control that allows to improve the dynamic performance of the power converter in the presence of bounded perturbations and significant changes in operating region. The results of the simulation of a 1 kW converter are presented. It is shown that it is possible to raise power factor up to 0.996, to decrease the deformation of the zero crossing and to reduce the total harmonic distortion in the input current down to 2.8%, keeping it below the maximum permissible limits of the standard EN / IEC 61000-3-2 (1000-3-2).

Summary Residential photovoltaic power plants (RPVPPs) have a wide area of utilization in PV applications. Thus, low‐voltage penetration of these plants to the grid is a crucial issue for the high efficient operation of a photovoltaic (PV) system. The conventional maximum power point tracking (MPPT) methods have some drawbacks. Thus, intelligent MPPT methods are proposed in the literature to achieve these problems. This paper presents a new real‐time fuzzy‐based MPPT controller design for a new high gain transformer‐less and single‐switched power boost converter operating with different duty cycles for PV‐based residential applications. The proposed structure can ensure an enhancement in voltage gain by eight times for duty cycle of 50% that is much more effective than a conventional boost converter that can gain the input voltage to two times at the output of the converter. The higher amounts of the DC voltage gain are possible by adding the novel and efficient switched capacitor (SC) blocks. The proposed control method uses designed fuzzy‐based rules to control the duty cycle of the implemented power boost converter in the real‐time domain. A data acquisition card is used to control the duty cycle and monitoring the PV system. The proposed fuzzy‐based algorithm is performed in advanced LABVIEW software. The experimental results show that the developed fuzzy‐based controller is independent of the circuit parameters and has a more reliable response for changing environmental conditions. The accuracy of the applied fuzzy‐based MPPT method in the tested PV system varies between 95.8% and 99.6%.
